ments in the supporting frame, whereby it is made rigid, and so constructed to prevent the beater plnions becomlng disengaged from the operatlng wheel.

The object of the present invention isto,

form a brid e integral with the supporting frame, said bridge extending under but adv jacent the pinions, whereby the pinionstare prevented in transit, or in operation, from becoming disengaged from the operating wheel.

In the accompanying drawings:

Figure 1 is a side elevation of a heater which embodies my present improvement.

' Fig. 2 is a view of the upper end of the beater taken at right angles to Fig. 1.

Fig. 3 is a top plan view of the supporting frame.

Fig. 4: is a horizontal sectional View taken through the lower part of the supporting frame. 7

Fig. 5 is a reduced plan view showing the blank out of which the supporting frame with its integral bridge is formed.

In the type of beaterhere shown, there are two heaters 1 and 2, which extend parallel to each other and have their outwardly bulged portions 3 interlocking. This form of beater is provided with a substantially ikshaped wire member 4, which passes through the lower ends of the bulged portion 3 of the blades, and through pinions 5, which are attached to the upper ends of the beater blades 1 and 2. V

The present improvement pertains to the supporting frame. which consists of a vertically formed portion 6, its lower end being bent into substantially a U-shape 7. Attached to the vertical portion or arm 6 of the frame is an operating gear'wheel 8, to which is attached a suitable operating handle '9. The teeth 10 of the operating wheel 8 eX- tend between the inions 5 and engage both of them, whereby the operation of the wheel 8 causes the two beater blades 1 and 2 to revolve in opposite directions. Thus far, I have described the ordinary construction of this type of heaters.

One improvement ofthis application is to forma bridge '11 in the lower portion of the U-shaped part 7. This bridge is integral with the horizontal portions of the U-shaped part 7, and as shown in Figs. 1 and 2, the bridge is located under the pinions 5, but adjacent thereto, whereby the pinions cannot be moved downward to cause them to disengage the teeth; 10 of the operating wheel 8. The additional function of this bridge portion is toafiord rigidity to the U-shaped bent portion 7, of the supporting frame, whereby it [is held more firmly against being bent I inf transportation or otherwise. 1 I V.

It is the primary object ofithe prese'nt in vention to make the beater as rigid as possible, and at the same time prevent the pinions from becoming disengaged with the teeth 10 of the operating wheel.

The pinions 5 can become disengaged should some part of the beater blades 1 and 2 be bent in a manner to shorten them,

thus pulling the pinions attached to their upper ends downward, which would either cause the pinion to disengage the teeth 10, or be in such a position that it would not properly operate. This is impossible with the integral bridge herein described.

The supporting frame is stamped from sheet-metal, in a manner to form the bridge 11, after which the supporting frameis bent to the shape shown in the accompanying drawings. 1

The upper ends 12 of the rod 4:, are attached to the sides 18 of the U-shaped part of the supporting frame in any desired manner, as the manner of attaching the wires forms no part of my present improvement. V

The handle 14% may be attached to the arm 6 of the supporting frame in the man ner here shown, or in any desired way, since that forms no part of the present improvement. 1 i

It is highly desirable to form a support ing frame which is rigid and which prevents the disengagement of the pinions from the operating gear wheel, as herein described. It is found that a supporting frame constructed as defined herein is vex y rigid and is a desirable practical improvement over the frames heretofore con structed g I am aware of the construction of a ERNEST Hanson HUMPI-IREY, or New BRITAIN, connncrzon r Assrenor.

bridge which is made of a separate part,

to the supporting frame; 7

In the present improvement there is practically no additional expense, because the supporting frame is stamped from sheetmetal with the integral bridge 11, whereby .it does not require an additional stamping operation, and when the frame is completed, it adds much rigidity to that part of the beater which supports the beater blades, which is the point Where the strain comes.

By reference to Fig. 5, whichis a reduced plan view of the blank for the supporting frame, it will be observed that the blank has one end provided with parallel openings 15, 1

forming between them the above-mentioned integral bridge 11.

Having thus described my invention, what I claim and desirev to secure by Letters Patent is:

1. A beater comprising a supporting frame having its lower end substantially U-shaped, the horizontal portion of the U-shape having longitudinal openings at each side of its center, the inner sides of the openings curved inwardly forming an integral bridge with a reduced central portion, and enlarged end portions, for the purpose described; I

2. A heater 7 comprising a supporting frame having its lower end enlarged and substantially U-shaped, the horizontal portion ofthe U-shape, having openings which extend. up into the vertical portions of the U-shape, and the horizontal portion provided with an integral longitudinal bridge, for the purpose described. 7

In testimony whereof I hereunto affix my 7 signature.
